The Different Types of WeatheringWeathering

Physical and Chemical breakdown of rock

Physical

- Root Pry

-Exfoliation

-Frost Action

-Wind Abrasion

Chemical

- Oxidation

- Acid Rain

Why is this rock red?

OXIDATION

Root Pry

What will happen to the rock the tree is

growing in.

The rock breaks apart

Exfoliation

Peeling away of rock. This

makes the half dome.

Frost Action or ice wedging slowly breaks

up this sedimentary rock into unusual shapes.

What could have caused these rocks to become rounded.

WIND ABRASION

Acid Rain

1908 to 1969

What could have eaten away this statue?

Erosion

Process of wearing away the earth’s surface.

Types of erosion:• Wave Action

• Running Water

• Landslides

• Avalanche

•Glaciers

• Slump

•Creep

• Rock Fall

• Mud Flow

Wave action - when waves hit the rocks and pieces of rock break off.

Running water eroded the sides of this canyon and created the V-shaped valleys.

Mass Wasting - landslides

A slump is when a clump of earth breaks apart and falls

Creep.

Land slowly slipping over many years from temperature or water.

This avalanche is an example of

Mass Wasting

This glacier carves out a U-shaped valley by dragging rocks and boulders

with it

Deposition

• When erosion stops and particles that were moving are settled in a new location.
